Together, the iMac and the MacBook Pro are trouncing the PC.

Apple's new CEO Tim Cook revealed some new sales numbers ahead of the iPhone announcement that should have investors pleased.

Specifically, Cook announced that the iMac and the MacBook Pro are now the best-selling desktop and notebook computers respectively in the United States.

Cook affirmed that the Mac operating system platform has grown by 23 percent since last year, while the PC has only grown by four percent. As Apple approaches having 60 million Mac users worldwide, the Cupertino, Calif.-based corporation now retains 23 percent of the market share as of August.

On the music front, the iPod has stayed strong with 78 percent of the portable music player market share.

Cook pointed out that more than 300 million iPods have been sold, whereas it Sony approximately 30 years to sell 220,000 Walkman cassette players. That almost seems like an unfair comparison, considering how cheap iPods have gotten (look at the iPod Shuffle), and cassette players were never considered as cool as the iPod at any point of its history.

Nevertheless, Apple doesn't look to be giving up on the iPod as it sold 45 million iPods between July 2010 and June 2011. Cook proposed that almost half of those are still going to first-time iPod buyers.

Finally, Cook asserted that iTunes is still the top digital music store in the world with 20 million songs available (twenty times than what iTunes commenced with) and roughly 16 billion tracks downloaded.
